Embodiment Construction

[0040] The present invention will be further described by way of examples below, but the present invention is not limited to the scope of the examples.

[0041] This embodiment is applied to a TV including a SoC chip and a TCON board. Specifically, the SoC chip transmits a digitally processed video signal to the TCON board. The video signal is processed by the TCON board and converted into a video signal capable of driving the display screen to display images. signal.

[0042] In the existing technology, such as figure 1 As shown, the SoC chip (transmitting end) transmits the video signal to the TCON board (receiving end) through the serdes line. If the serdes line is interfered, the video signal received by the TCON board will be inconsistent with the video signal actually transmitted by the SoC chip. At present, the TCON board feeds back the status of the received video data to the SoC chip through a single connection line, including normal and abnormal states. For example, feedb...

Abstract

The invention discloses a TCON board, a method for signal transmission from the TCON board to an SoC chip, and a television. The method for the signal transmission from the TCON board to the SoC chipthrough a single connection wire comprises the following steps: analyzing a video signal transmitted by the SoC chip to obtain video data; if the video data is normal, transmitting a first level signal to the SoC chip; if the video data is abnormal, searching a preset table for an abnormality code corresponding to abnormal information of the video data; generating an indication signal used for indicating the abnormality code according to a protocol between the TCON board and the SoC chip; and transmitting the indication signal to the SoC chip. Compared with the prior art, the TCON board, the method and the television provided by the invention have the advantages that under the precise that hardware structures are not changed, more effective information can be transmitted to the SoC chip through the single connection wire between the TCON board and the SoC chip, so that effective information interaction between the TCON board and the SoC chip can be guaranteed, and the system reliability can be improved.

Description

Technical field [0001] The present invention relates to the field of television, in particular to a TCON board and a method for transmitting signals to an SoC chip, and also relates to a television. Background technique [0002] serdes is the abbreviation of English SERializer (serializer) / DESerializer (deserializer). It is a mainstream time-division multiplexing, point-to-point serial communication technology, that is, multiple low-speed parallel signals are converted into high-speed serial signals at the sending end, passing through the transmission medium (optical cable or copper wire), and finally at the receiving end High-speed serial signals are reconverted into low-speed parallel signals. This point-to-point serial communication technology makes full use of the channel capacity of the transmission medium, reduces the number of transmission channels and device pins required, increases the signal transmission speed, and greatly reduces the communication cost. [0003] At pre...
